British thermal units (BTU) to Megajoules (MJ) Conversion
British thermal units
The British thermal unit (BTU) is a unit of energy approximately equal to 1,055.06 joules, defined as the energy required to raise the temperature of one pound of water by one degree Fahrenheit. It remains the standard unit for heating and cooling capacity in HVAC systems in the United States: air conditioners and furnaces are rated in BTU/hour. A typical residential air conditioner is rated at 5,000–24,000 BTU/h. One BTU equals approximately 0.000293 kWh.
Megajoules
The megajoule (MJ) is a unit of energy equal to exactly 1,000,000 joules (10⁶ J). It is used in energy policy, engineering, and physics for large-scale energy quantities. One kilowatt-hour (kWh) equals exactly 3.6 MJ — the conversion fundamental to understanding electricity bills. A litre of petrol contains approximately 34 MJ of chemical energy. The explosive yield of conventional explosives is sometimes expressed in megajoules.
